Referring ro 'ehe irai-ings in detail, the numerall clesignales a box in the front of which is an aperture 9. in which is mounefl an image screen 3. This screen is provided with a pluraliy superimposed images. the separate images heilig ciepiciccl in conirasn ing colors such as red and hlue This screen or plate is lransparenl or ranslueeut. and in le if? is'ransparen'c one iinafije maibe loaned on one surface Yai. while the other iniagena): he formed on the opposite surface For purposes of illustration l have sluimu these images to he a hoyf ami a ruche T.

s'ape or bell; is a source of lighlll whichv may be an incandescent elecrie lamp, and a reflector 15 adapted to cause powerful light rays lo pass through liatpoi-lion of the tape or bell adjacent to the image sereen. and 60 after passing througlihe'lape or belt to illuminate the image screen.

The heliA l is composed of two halves joined shown at 16 and l?, one-half of the belt. for exampletlie upper half in Figs. l e5 and 9.., isinade of any suitable flexible trans lucent or transparent nia'erial aud may he colored refrl, as indicated by the if'erieal lining in Fig. 1. 'l'he lower half of ehe hell; may be constructed as indieaefl in these "'G figures of any suitable *flexible rafiisluceni, or transparent material and ma;7 he colori-ul blue.. as indicaed by the liorizfin'al lines in Fig. l.

lt will he obvious freni *he eoi'isruction above described that the porlxion of ihe hell, which is colored blue anal which at any time may be situated between the soufre@ of light and the image screen will cause blue light to shine through she screen, and. similarly, the 8G reel portion of the ape or hell which is oe-- 'tween the source oi light and the image screen will cause, red lighl;` to shine "elirougli lie adjacen porion of llie screen.

TWhen blue light is caused io shine "ihren"1 the plate. au observer 'ioolringg' a@ 'die pla 3 through the aperture 2 will see that portion of the image which is clepivcrl in rerl an ii will appear to him as sulistanially black rupon a blue background, Simultaneously, so the image which is depicted in blue will lie` come substantially invisiblef having merged into the general blue ione cast upon the background. lu a similar inanneiu when rerl light is caused lo shine tlirol'xgh the im $5 al1-e screen. that portion of *die picui'e which is depicted in blue will appear lo the ohser'ver in lilaclr against a red background into which has merged the refl portion of the picure hecause ol the red hue cast upon lhe lmrkgrounil hy the refl light passing through the screen. The appea ance of the courasliuq' color as hlacli in eaoh case. is (lue to the well-known fact lhalthe pigiueuj or other uiaerial which appeared le hlue hy transmiltell light has liis property because il shus oil all rays exrepl. blue. aufl therefore will -eilecually har lie luis sagre of llie red rays. resultingjin an un pression of hlackupou the eve. The same 11i) principle holds with respect to the blue light transmitted through the red coloring mat-A tei'.

The general result ot the operation .above described will be to cause an alternation in the pictures seen. As clearly indicated in Fig'. l, the ligure ot' the boy will appear whenever red light is transmitted 'through the screen. and the picture of the yacht will he seen when the blue light is transmitted through the screen, thus causing a dissolving view of an extremely novel effect without projecting the images.

In Figs. 3, t and 5 l have illustrated a modification in which an endless translu, cent belt 18 passes over rollers 19, 20, 2l and 2Q. This belt corresponds to the imam: sei-een 8, excepting- 'for the tact that it is flexible and contains a plurality of superimposed pictures 3 and 21'- ol contracting colors illustrated in Figs. 4 and These pictures may be either directly superimposed upon the same surface or may be placed upon opposite surfaces Z5 and 26 in case the belt is transparent and not merely translucent.

The roller is driven from the motor QT by means otsears QQ, 2S). SO and 3l -which form part ot an intermittent motion by which the uniform rotation ot the shaft of the motor Q7 is changed into an intermittent rotation of the roller 22. For purposes of illustration l vhave shown the well-known Geneva motion, which need not he described in detail, but any other suitable mechanism for achieving this intermittent transmission of rotation may be substituted, as will he obvious. V

llpon the. shalitot the gaar 29 is mounted a dish 3Q carrying a segmental contactor 33 which passes under the brush 3l forming part ol the electrical circuit 35, 3Q., of which a source of red light 37 is a part. The mechanisin is so proportioned that duringr the intervals ot rest of the roller 22 the segmental contacter 23 will pass under and -in contact with the brush 3l, so as to forni a coniplete electrical circuit through the lamp or other source ot' illumination, causing' red light to shine through the tape. Therefore, during' the periods when the lamp is dark the tape -ill be moved to a predetermined distance -equal to the length of a picture. 'lter thetape has come to rest. thc lamp will automaticall)v flash duringone-half the 'interval of rest of the tape.

lf the images 221i and 24 are superino posed as in the case of the construction of pale tint. itwil be practically unnotieeable when the la'inp Irl? is darl: and the image is viewed by reflected natural or artificial light troni the outsideol' the box. when the lamp dashes aiid'red light pro.- iected through the screen` the blue picture lloweyer,

source of energfygby the wire G3.

will stand out black, or substantially so, against a red background into which the red picture has merged because ol: its similar tint. The result, so far as the observer is concerned, will he similar to that produced by the construction first described.

In Fig. 6 l have `illustrated a inodiication wherein a second source ot' illumination 38 is provided, so that nov reliance is placed upon daylight or other means ol' illuniination normally existing' outside of the box. The structure is otherwise the saine except for the tact that two brushes, 39y

and 4.0, diainetrically arranged with reslie'ct to the segmental contact-or S3. are now provided. Wire l1 leads from. the brush Si) to thelamp iftmm which the wire lf2 leads to the source of electrical energy 4f), the circuit being completed through the wire #il leadino to the segmental contacter. lire 45 leads rroin the hrusli l0 to the lamp 38.y which is in turn connected by the wire 4G to the wire l2 at the point 47, the re niaining portion of the wire 42 serving as a conductor to the source oiu electrical energy. "By this arrangement .itwill be seen that instead of a single light alternately flashing' and remaining' dark through one-halt of the period of rest olf the rihhon or screen. the lights will alternately7 flash, one or an other of the two lights always being lighted hiring` the period ot rest of the ribbon or screen. lu the case of this modification the light 3S inay preferably be blue in color in order to nialre the cutting out ol the blue picture more eertain. and in this ease the original tint of the blue picture may lic holder.

Fig'. 7 illustrates a iiiodiication in which the box 48 provided with a substantially central partition-lf) and with an aperture 5() in one side. ln the partition is mounted a screen or plate 5l. ot' transparent material such as glass, upon which is inscribed a picture 52. preferably in blue. ln baci( ol the` screen is a slielt on whieu may he placed any suitable article such as the clock 54, which it -is desired to show in connection with the picture on the screen. ythe hinged door 55 permits the replacement of this arti cle as desired. In front ot' the screen is mounted a redlamp 5G, and behind the screen'fbiit in front of the clock or other el ject to be shown is placed a blue lamp f5?. A source oliA electric energy 5S supplies current to these lights in alternation, the path of the current beingI through the wire F39 to the segmental contact ($0 on the disk Gl, which is constantly rotated by any suitable source of power. From the contact T30, When 'the parts are in the positionA shown' in Fig. 7. the current passes through the brush 6l, wire 62, the lamp 5G, and thence haelt to the W'lien the segment is in contact with the other brush 'Isl l-l, the current will pass through the wire 5), segmentv (il). brush lS-l. wire G5.' lamp 5l', wire (SG, and wire (323. i.

llhen the red light 56 is lighted and the blue light i? is darli. an observer looking through the aperture 50 will see the picture 5;), upon the screen. This picture will. appear substantially black. since the blue, coloring mattei' has the propert)7 of reflecting only blue rays ot light. The background will be colored red by the light 5G, and. the clock -l or other object will not be seen, be cause the flooding ot the 4screen with the red light 1from the front will act to prevent the observer seeing the unilluininated object behind the screen'. Tihcn. however. the blue light 5T is lighted and the red light 5; is extiuguished, the object 5i will be seen by the observer. 'for the reason that the blue picture on the screen will thenfuierge into the general blue tone o'iren to the screen by the light. and 'the object. now beingstronglv illuminated. will be risible through this light blue tint ot the screen. lf a picture such as that shown in Fia'. 2-3 is depicted upon the screen. the observer will alternately see the picture and thel object. and a relation 'of canse and etect useful in advertising and other purposes. will'be obvious. .may be produced.

ln Fig'. il l have illustrated a modification which is in niany ways an extension of the idea embodied in the forni ot apparatus shown in Figs. 3 to 5. inclusive. ln this tjvpe the bor; is provided with an aperture o8, behind which is rotated the belt 69 carried by the pulleys T0. Tl. (2 and 73. lininediately behind the belt' (39 is a second belt il carried on the rollers 75, 76. 7? and 78. @ne ot' these belts is provided with a series ot pictures in blue. whilethe other is provided with a series ot pictures in red. so that the two belts taken together correspond to the single belt illustrated in Figs. l and 5. The belt (i9 is driven by the pulleji7 7:2 through an intermittent motion T9 troni the uiotoi' Si). The belt T-l is similarly driven bfi' an intermittent motion Sl from the saine motor. l have illustrated the well-known Geneva motion. but it will be obvious that an;v other suitable motion ma)Y be substituted. The gearing' is so proportioned that the belts more intermittenti).v but in svn chronism and at the saine rate ot speed. so that although the belts are of different length the pictures on the two belts immediatelyv behind the aperture i9 will alwavs register. that will be in alinenient so far as their centers or borders are concerned. Since the belt Tl isniuch shorter than the belt Si). at,

the end of a complete revolution of the belt.

T-l. the lirst picture ou the belt T-l will not register with the first picture on the belt G9, but with Sonie other pictureA so that the duplication of pairs of pictures will be elr'ected only at long intervals.'depending upon the number ot' pictures on each belt. and'conse quentl;Y uponthe lengthsy ot the belts. Ithere, is mounted within the box means tor illuininating' the pictures in register. includinglr a red light Si). and a blue light S3, which are lighted in alternation 'troni any suitable source oil electrical current .C3-l by means ot' a flasher 85 which ma): lbe similar to thoge already described. except that the rotating segmental contact S6 is substantially less than 180 degrees in angular length and is made sufficiently short so that neither light is lighted during the period when the belts are being' advanced to bring' a new pair ot pictures before theaperture.V

ll'hile lA have described in)7 invention throughout in connection with red and blue colors tor the contrasting images. it is ohvious that other sets otl contrastingY or primary colors nia)Y be utilized. although l re iard the rfd and the blue as most advantageous owing' to tlie'tzu't that ther lendV theniselx'cs readihv to printing and other methods of producing imanes of the character described, i
